Application 11 Claims.

This invention relates to a drawing in frame and has for one of its objects the provision of an entering frame in which unnecessary lifting of the warp roll is eliminated, in that means are provided for receiving the warp roll in a lowered position an preferably from a truck as disclosed in co-pending patent application, Serial Number 510,048, filed on the th day of January 1931, by John G. Bentley.

After the warp roll is received into the drawing in frame, means are provided for hoistingthe warp roll to an elevated position and automatically stopping in proper position where the warp roll will rest while the threads are entered then thru the comb and then secured to a takeup roll which has means for holding the same in adjusted position. After the above entering operation has been completed, the hoisting apparatus can be started and the warp roll will be lowered to its original position and in which position the drop wires may be installed and when these drop wires are installed the warp and harness and combs and drop wires and take-up roll are all ready to be installed in a loom.

Heretofore, it has been the practice in the old types of drawing in frames to summon two or more men to hoist the warp roll to an elevated position by manual means and then to secure the same by a rope or on hooks and the like and then when the warp roll is to be lowered to its lowermost position for the placing of the drop wires, it is then necessary to require the services of two or three men to move the warp roll to the lowered position for the installation of the drop wires. r By means of the improved structure set forth in this application, it is possible for the operator of the drawing in frame, that is the one engaged in entering the warp into the heddles and the like, to operate this drawing in frame to raise the warp roll by any suitable means such as an electric motor and to lower the same to lowered position without the necessity of summoning additional aid for the raising and lowering operations. 1

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is a front elevation of the drawing in frame; Figure 2 is a side elevation of the drawing in frame, showing the parts inposition for installing the drop wires;

Figure 1C- is a sectional View taken along the line10l0 in Figure 9. Referring more specifically to the drawings, the numerals l0 and 11 indicate the upright members of the frame, and these members 10 and 11 have therein the vertical slots 19a and 11a respectively. Members 136' and 129, which will be later described, pass thru and have slidable contact with slots 10a and 11d respectively. The lower ends of members 10 and 11 are secured to base members 12 and 13. These base members 12 and 13 are in turn secured together by another base member 14. Members 10 and 11 at the upper end thereof are secured together by a cross member 15. Secured to member 15 are two upstanding members 16 and 17 which have a plate 18 spanning the distance between them, and fixedly secured to their upper ends. This forms a base fora reversiblemotor 19, said motor having pulley 20 with an endless belt 21 thereon passing over and around another pulley 22. Leading from the motor is a conduit 23 which leads to a reversing switch 24 which is fixedly secured by means of bolts 25 and 26 to member 10. Leading from this switch is another conduit 27 which leads to a source of power 29a, and this switch has thereon an arm 28 to which is fastened a switch rod 29, said switch rod being slidably mounted in an outstanding lug 30 which is fixedly secured to the front face'of member 10. Fixedly secured on rod 29 is a lug 31 with handle portion 32, and near the lower end of rod 29 is fixedly mounted a lug 33 which has the outstanding portion 34. Around rod 29 and between members 30 and 33 is mounted a coil spring 35. Near the upper end of this rod is mounted a member similar to member 33, this member being designated by the reference character 37, withoutstanding portion 38. The members 33 and 37 are adapted to be struck at times by certain of the parts to stop the motor, the action of which will be later described.

On member 15 near one end thereof is fixedly mounted an upstanding member 40, having bearing portions 41 and 42, and at the upper end thereof has a U-shaped portion 43 which has in one leg thereof a bearing portion 44, and on the other leg thereof has a bearing portion 45. Mounted'in bearing portions 44 and 45 is a shaft 46 which has thereon a worm 47, and the pulley 22 (see Fig. 4). Near the other end of member 15 is mounted an upstanding member 48 which has at its upper end a bearing portion 49. Mounted in the bearing portions 41, 42 and 49 is a shaft 50 which runs parallel to member 15, and mounted on this shaft 50 at one end thereof is a drum 51, and on the other end thereof is mounted a similar drum 52. Between these drums and in close proximity to bearing portion 42 is mounted a worm gear 53, meshing with worm 4'7.

Fixedly secured on the upper surface of member 15 are the two backwardly projecting members and 56 (see Figs. 1 and 2), these members being made of angle iron and having mounted at their rear ends downwardly projecting U-shaped members 57 and 58 for receiving beam 215 when not inuse. On the under surface of these members 55 and 5 6 are mounted wooden strips 60 and 61. Mounted in these strips 60 and 61 is a plurality of hooks 62 which pierce holes 63 in strap members 64, there being a plurality of these holes 63 in each strap member 64 to allow for adjustment. At the lower end of strap members 64 are holes 65, there being a plurality of these holes 65 in each strap member to allow for adjustment. Piercing holes 65 are hooks 66 which have secured thereto cord members 67 which have secured at their lower ends threaded rods 68 which threadably engage a turn buckle 69. Removably mounted in the lower end of turn buckle 69 are members '70 which are fixedly secured to harness 94 and 95, is a shaft 101 which has a drive fit in frames 7-1, 72, '73 and '74.

On the underneath surface of members 55 and 56 and running longitudinally with member 15, is a rod '75, and near each end of this rod are mounted the cord members '16 and 77. These members '76 and 77 have therein loops '78, '79, 80, 81, 82 and 83. These members '76 and 77 are secured at their lower ends to member 14 by means of hooks 85 and 86 passing through loops 8'1 and 88.

Mounted around drum 51 and fixedly secured thereto is a cable 90, and this cable 90 projects downwardly and into hollow upstanding member 11 and fastens to a dog 91 forming a part of a safety mechanism disposed in each upright 10 and 11 which is mounted in a slidable member 92 which is also on the interior of member 11. This dog 91 is mounted on a pin 93 which is mounted in the sidewall portions 94 and 95 of member 92. This shaft 9.3 has a non-rotatable drive fit in the sidewall portions 94 and 95. and the ends, thereof arepeened to further fixedly secure this shaft 93. Dog member 91 has the lower end thereof serrated v asat 96, and at the upper end thereof has an outstanding lug 9 7 in which is mounted one end of a tension spring 98 which projects downwardly and is secured to a pin 99. mounted in sidewall portion 100 of member 92. Near the upper end of member 92, and mounted in the sidewall portions the. sidewall portions 94 and 95.

The ends of the shaft 101 are peened as at 102 and 103, and rotatably mounted on this shaft 101 are rollers 104 and 105. Portions of the sidewall 100 are cut away as at 106 and 107 to allow these rollers 104 and to have contact with the inside of member 11. A tongue portion 108 which is left when the openings 106 and 107 are cut in member 100 serve to space the rollers 104 and 105. Near the lower end of member 92 and similarly mounted are the rollers 110 and 111 on shaft 112 which project through sidewall portion 113 of member 92.

Slots 114 and 115 are cut to allow the rollers 110 and 111 to pass through sidewall 113 and have contact with the interior of member 11. In cutting these slots a portion 116 is left in sidewall 113 to serve as a spacer for the rollers 114 and 115. The above arrangement is present in each upright 10 and 11 and forms a safety mechanism which prevents falling of the beam in case either of the cables breaks.

Mounted on the outside of sidewall portion 100 of member 92 is a forwardly projecting arm 120. This arm 120 has the short portion 121 which has one end thereof notched to form the lugs 122 and 123. The other portion 126 of arm 120 has lugs 124 and 125 thereon and by passing a bolt 12''! thru these lugs it is seen that a hinge joint is formed between the portions 121 and 126. Mounted on the inside face of member 121 and projecting inwardly is a pin 128, the purpose of which will be presently described. At the forwardend of member 126 and near the upper edge thereof is a U-shaped bearing 130.

Passing around drum 52 and fixedly secured at one end thereof is a cable and this cable projects downwardly and into the interior of member 10, and the other end thereof is fastened to a member similar to member 92 in every detail except that it has the forwardly projecting arm 136 which has the inwardly projecting pin 13'? and a U-shaped bearing 138 at the outer end thereof, and this member 136 is similar to member 120 except that it is not hinged as at 127.

Fixedly secured to the exterior of member 10 is a circular plate member 140 having an outstanding bearing bolt 141 on which is pivotally mounted a circular plate member 142.

Member 142 is secured in position by means of washer 143 and nut 144 and projecting from plate member 142 is an arm 145. Arm 145 is round in cross section and has an inwardly projecting portion 146 and a backwardly projecting I portion 147 and an upwardly projecting portion 148, and in the upper end of this portion 148 is a u-shaped bearing 149. Pivotally mounted on the portion 145 as at. .50 is a pawl 151, the purposeof which will be presently described. Member 142 has an outstanding boss 152, which boss has a circular cavity 153 in which is slidably mounted a pin 154 which is adapted to fit in cavity 155 in member 140 at certain times. This pin 154 has a smaller portion 156 which has thereon at the outer end thereof abutton 157 which button is adapted to, be gripped by the fingers to pull pin 155 from engagement with portion 140. Mounted around portion 156 and in the cavity 153. is a compression spring 158 which normally forces pin 154 into cavity 155. Mounted on the exterior of member 11 is a plate member 16.0 which is similar in detail to plate member 140, and pivotally secured to member 160 is a plate member 161 which is identical to member 142, and projecting from member 161 is an inwardly and backwardly and upwardly projecting arm 162, this arm having at the top of the upwardly projecting end lg-shaped bearing 163, and this arm is similar in detail to arm 145 except that it does not have the pawl 151.

After the warp has been slashed and wound on the loom beam 175 it is then brought to this drawing in frame and may be' brought on a truck or by any other suitable'means; Beam 175 has a shaft 176 passing therethrough and extending from each end thereof, and the beam has drum portions 177 and 178 on the respective ends thereof. The portion 126 of member 120 is swung outwardly and one end of shaft 176 is placed in bearing 138 and then member-120 is swung back into position and the other end of shaft 176 is placed in bearing 130, the purpose of the swinging of member 120 is to make it possible to engage shaft 176, in bearing 138 without unduelifting. The ropes 180 and 181 are passed several times around the drum portions 177 and 178 respectively, and rope 180 is secured 'to' pin 128 in member 120 by means of a loop in one end thereof. The other end of this rope has a loop 184 in which the hook portion of a weight supporting member 185 engages. This weight supporting member having thereon removable weights 186, 187 and 188, and rope 181 is secured at one end to pin 137 in member 136 by means of a loop 183, similar to loops for rope 180. The other end of rope 181 has loop 189 in which is mounted the hook portion of a weight supporting member 190 on which are mounted removable weights 191, 192 and 193. The beam is now in condition to be raised to the position shown in Figure 5 for entering the warp threads thru the harness.

The only weight necessary to be used for the following operation is the weight 193. As it is desired to move the beam upwardly, the operator grasps handle 32 of member 31 (see Fig. 1) and moves it upwardly. This throws the switch 24 and causes motor 19 to rotate clockwise in Fig. 1 and thus causing the drums 51 and 52 to move clockwise in Fig. 2 and wind the cables 90 and 135 therearound. This imparts upward movement to the member 92 and the arms 120 and 136 on which are mounted bearings 130 and 138 in which the end portions of the beam shaft 176 are mounted causing the beam to move upwardly. The beam moves upwardly until member 136 strikes portion 38 of member 37 onswitch rod29. This opens the circuit to the motor and stops the beam in the position shown in Figure 5. The beam is in position for the drawing in process to begin. Lease rod 200 is slipped thru loops 78 and 81. Similar rods 201 and 202 are passed thru the loops 79, 82, (Fig. 1) and also and 83 respectively. The warp threads are then passed over rod 200 and to the left of rod 201 (Figure 5) and every alternate thread is passed to the left of and beneath rod 202, and the other half of the threads are passed to the right of rod 202. The threads are then passed through the heddles 71 to 74 and alternate threads are passed above rod 205 while the other threads are passed beneath rod 205. Then all of the threads are passed thru reed 213.

Thislease rod 205 may be supported by any suitable means such as by tying it to the top of the harness frame with a cord 195., The warp is then passed thru the reed 206. Thisreed is supported by two brackets 207 which brackets have the upwardly extending portions 208, laterally extending portion 209, downwardly extending portion 210, the laterally extending portion 211, and the upwardly extending portion 212, the

a same being supported in the harness frames.

After passing thru the reed, the warp is then tied asat213. m1

, The arms 147 and 162 are now moved to the position shown in Figure 2, being held in position by means of pins 154 engaging cavity 155 in memher-140 (See Fig.8). A beam 215 has thereon a ratchet wheel 216, this beam having bearing portions-217 and 218, and this beam has fixedly secured thereon oneedge of a piece of fabric 219, the other edge of this fabric having secured thereto the'rod 2 20. The fabric 219 has notches 221 therein where it is secured to rod 220 to permit bunches of warp threads to be passed there through (Fig. 7). The bearing portions 217 and 218 of beam 215 are placed in bearings 149 and 163 on arms 145 and 162 respectively, taking a position as shown in "Figure 2.

The rod 200 is then removed and the operator grasps portion 32 of member 31 and pulls it downwardly. This reverses and closes switch 24'causing the motor to rotate in a counter clockwise motion in Fig. 1 and causes the cables and 135 to unwind from drums 51 and 52, thus moving member 92 and its associated parts downwardly until arm 136 strikes portion 34 of member 33, thus pulls switch rod 29 downwardly and opens switch 24, thus stopping the beam in the position shown in Figures 1 and 2.

The lease rods 201 and'202 are removed from loops 79, 82, 86, and 83 and are drawn to the position shown in Figure 2.

The reed is raised from the position shown in Figure 5 to that shown in Figure 2, and the lease rod 205a is inserted on the other side of the reed 206 and rod 205 is withdrawn from the position shown in Figure 5 and is discarded. The ends of the Warp are now tied around rod 220 as at 225 (See Fig. 7). Tension is now applied to the warp by moving ratchet wheel 216 in a clockwise direction in Fig. 2, and the pawl 151 prevents this ratchet wheel from slipping backward or in 'a counter clockwise direction in Fig. 2 when tensi'on is applied to the warp.

A plate member 225 having spaced holes thereinto accommodate the rods 201 and 202 is applied over the ends of these rods. A similar plate member 221 is placed over the other end of these rods, and these plate members have notches in which are placed the ends of horizontally extending bars 222 and 223 (See Fig. 2). These bars 222 and 223 serve as a support for the drop wires 224 when they are placed over the warp. After all of the drop wires are placed over the warp as shown in Figure 2, the warp is untied from'r'od 220 and tied behind lease rod 205a as shown at 230 in Figure 7. After all of the warping is tied behnd the rod 205a, the warp is in condition to be moved to the loom. The plate members 220 and 221 are removed from the ends of rods 201 and 202, the-harness frames are detached from the straps 64, the ropes 180 and 181 are removed from the drum of the warp beam, and the warp beam is rotated in a counter clockwise motion in Fig. 2, thus drawing the lease rods20l', 202 and. bars 222, 223, and the associated drop wiresfthe harness frames, the reed and the lease rod 205a therearound it, or as nearly so as possible.- The beam is then taken from the drawingin frame to the loom. r

When the warp is removed from rod 220 and secured to rod 205, the beam is placed in hooks 57 and 58 where it remains until the frame is again used, as shown in Figure 5.
